My local dealer is actually well stocked on spares.
The dude there helped me compile a bar from scratch for my huge antique 2007 Contra and also had a Leading edge for her in stock. They had no old spares on their site but a phone call later I was sorted out.

I guess its probably a big difference from dealer to dealer but its a pita if Cabrinha internationally is not sorting spare parts out.. But as mentioned above, alot of the stuff is similar and I would rather put a 2013 chicken loop, depower line and strap on the 2011 bar instead of keeping the non swiveling swivel up there...
